Do movies on an external Hard Drive degrade in quality over time?




ali g


Okay, so, here's my problem. I have this external Hard Drive and it has over 450 gigs of movies on it, now, somehow, they are all playing in 360p when I'm sure most of them were DVD Rips and the ones that weren't were Blu-Ray's. Additonal Info: The HDD in question has a strange connection cable, it folds out of the harddrive and plugs directly into the computer, great for efficiency but latley the little flashing light (data transfer I think) hasn't been shining as bright or at all sometimes, could this have something to do with it? Any help is appreciated, thanks guys/girls :) .


Answer
Partly no and partly yes. Data on any hard drive, SSD, flash drive, floppy, etc. is digital, not analog. With digital, you can either read an individual byte correctly or you can't read it at all. Because of that, when you have a problem, you see little squares of nothing within the picture or the picture freezes. You will not see the snow that older TVs had, ever.

It also means that the resolution of a picture/movie/etc will never change. When problems with the drive arise, you will see that pixelization or freezing, but never a change in resolution.

So, if you mean a change in resolution, no, it will never change. If you mean problems with the picture, then yes, it will happen eventually. Eventually may mean minutes from now or many years. You cannot predict when a hard drive will fail until it starts having problems. There are many factors that contribute to that, so there are things that you can do to help, but it's like predicting bad weather. We all know it will happen, experts can predict it within a few days, but no one can predict it months in advance.

The cable has nothing to do with this. The light also has nothing to do with it and is just a coincidence. The issue is that the movies were ripped at whatever resolution you are now seeing.

Disclaimer: technically, the drive can read individual bites incorrectly. I said it can't read a byte incorrectly because I already got too technical in explaining this. Since you don't see a byte that was read wrong, the effect is that it didn't read at all. It's much easier for people to understand if you just say it that way, but it isn't correct from a completely technical standpoint.

Do you lose quality when putting videos from your hard drive to your external hard drive?

Ok here is my story. I have to format my hard drive, but i dont want to lose my videos and my music. So I'm asking do i lose any quality on any of my music or videos, if I'm moving them to my external drive and back to my hard drive after formating my hard drive?


Answer
you probably don't need to format your hard drive , you can do most things you need to do with (free) software but there is no loss of quality with digital files, but be aware that if the external drive is fat32 the maximum file size is 2Gb if you transfer a larger file it may show as complete but only 2gb will have been copied, you will lose the rest if you format the original drive
